@techreport{oai:shiga-u.repo.nii.ac.jp:00008967, author = {Kato, Ryuta Ray}, issue = {No. 61}, month = {Sep}, note = {Technical Report, This paper proposes a characterisation of the optimal interaction between the patient and the medical doctor by incorporating scale transformation of distributions into a two-sided matching model. It also investigates the effects of congestion at the medical place, prolonged lifetime, as well as an increase in the doctor's salary on the optimal behaviours of the patient and the doctor.    It will be shown that there always exists a unique equilibrium pair of the patient's reservation utility and the doctor's reservation utility in the patient-doctor market with frictions, and that under a certain assumption of the distributions of idiosyncratic preferences, the patient's prolonged lifetime would induce increases in both the optimal reactions of the patient and the doctor. Since an aging population is partly caused by prolonged lifetime, both the patient and the doctor are more selective about each other in an aging society. Furthermore, it will be shown that an increase in the doctor's non-fixed salary decreases his own reservation utility and increases the patient's reservation utility. The congestion effect on the optimal reactions depends on the scale transformation of the distributions of idiosyncratic preference., 滋賀大学経済学部Working Paper Series, No. 61, pp. 1-31}, title = {Medical Doctors and Patients in a Two-Sided Search Model}, year = {1999} }
